If you click on Create Profile, a user profile will be created for you.

but there's no button to click, and if you press enter you get an error:

ImportError

cannot import name wikiaction

the solution is to create an account at dojotoolkit.org, and then use those credentials at dojocampus. here's the official word. and it looks like once you do have an account, trying to save any changes in the UserPreferences will result in the same error above
